Do they charge to fish there and do you need a license to fish..is there a place to buy bait there?

Excellent

They don't charge, but you always need a fishing license, unless (I think) you are fishing in freshwater, with natural bait only, no artificial lures. Check NC Wildlife rules and regs.

Not bait store , not sure about license

No there's no charge

No

I don't know if you need a license but they do not have a bait store
